What are the top 3 complaints from this month?

AI

Based on 247 submissions this month, the top 3 complaints are: 1) Slow checkout flow (mentioned in 31% of responses), 2) Confusing pricing page (22%), 3) Missing mobile support (14%). The checkout issue has been trending upward — it was only 18% last month.

You

Which day of the week gets the most submissions?

AI

Tuesday consistently gets the highest volume — 19.4% of all submissions land on Tuesdays. The quietest day is Sunday at 6.2%. If you're planning email follow-ups, Tuesday afternoon would reach the most engaged respondents.

Spot Trends

"Are satisfaction scores improving?" — get trend analysis across hundreds of responses instantly.

Understand Segments

"How do enterprise users rate us vs. small teams?" — slice your data by any field.

Find Outliers

"Which responses gave a 1-star rating but positive comments?" — surface contradictions.
